Abstract
The utility model discloses a front support of a liquefied natural gas cylinder of a passenger vehicle, which comprises a front distribution head, a rear distribution head, a connecting pipe, a supporting pipe, a gas-phase pipe, a liquid outlet pipe, a liquid inlet pipe and a molecular sieve. The front distribution head is connected with a seal head of a shell of the liquefied natural gas cylinder, the rear distribution head is connected with a seal head of an inner container of the liquefied natural gas cylinder, the gas-phase pipe, the liquid outlet pipe, the liquid inlet pipe and the connecting pipe are fixedly disposed between the front distribution head and the rear distribution head, the supporting pipe is sleeved outside the connecting pipe and fixedly arranged on the rear distribution head, mounting joints are respectively disposed on the ends of the gas-phase pipe, the ends of the liquid outlet pipe and the ends of the liquid inlet pipe, and the molecular sieve is filled at a gap in the connecting pipe. As the molecular sieve is filled at the gap in the connecting pipe, heat conduction path between low-temperature liquid at the front of the inner container and an outer seal head is broadened while keeping vacuum degree of an inner cavity of the connecting pipe of the distribution heads, and the front support of the liquefied natural gas cylinder of the passenger vehicle, which adopts the structure, reduces static evaporation rate of the liquefied natural gas cylinder of the passenger vehicle.
Description
Technical field
The utility model relates to the liquefied natural gas gas cylinder, refers more particularly to manned vehicle liquefied natural gas gas cylinder front support.
Background technology
The liquefied natural gas gas cylinder is a double-decker, and make cylinder liner with extraneous adiabatic by high vacuum multiple wraps technology, to reach the purpose of storing cryogenic fluids, and the support system in the liquefied natural gas gas cylinder has played inner bag and shell has rationally been fixed, make gas cylinder can bear acceleration, deceleration that vehicle is produced in motion, vibration during operation the time should be considered the requirement of strength that supports to reduce the static rate of evaporation of gas cylinder again as far as possible in design.
Manned vehicle liquefied natural gas gas cylinder front support is used for connecting the interior front head and outer front head of manned vehicle liquefied natural gas gas cylinder, and inner bag is played a supporting role.The static rate of evaporation of liquefied natural gas gas cylinder supporting construction intensity and gas cylinder is inversely proportional to, common liquefied natural gas gas cylinder front support structural strength is little, leaking heat is big, be unfavorable for the insulation of manned vehicle liquefied natural gas gas cylinder, make liquefied natural gas vaporization easily, it is too fast to cause pressure to rise.
Summary of the invention
Technical problem to be solved in the utility model is: the manned vehicle liquefied natural gas gas cylinder front support that a kind of high support strength, low static rate of evaporation are provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: manned vehicle liquefied natural gas gas cylinder front support, comprise: preceding dispensing head, back dispensing head, connection pipe, support tube, the gas phase pipe, drain pipe, feed tube and molecular sieve, preceding dispensing head is connected with the end socket of liquefied natural gas gas cylinder shell, back dispensing head is connected with the end socket of liquefied natural gas cylinder liner, connection pipe is fixedly installed between preceding dispensing head and the back dispensing head, support tube is set in outside the connection pipe and is fixedly installed on the dispensing head of back, be respectively arranged with the gas phase pipe on preceding dispensing head and the back dispensing head, the mounting hole of drain pipe and feed tube, the gas phase pipe, drain pipe and feed tube are fixedly installed on respectively in the corresponding mounting hole, gas phase tube end in the mounting hole, drain pipe end and feed tube end also are respectively arranged with erection joint, molecular sieve filled gap in connection pipe.
Described connection pipe is provided with the through hole that is used to load molecular sieve near preceding dispensing head place.
Be respectively arranged with some radial holes that are used to weld gas phase pipe, drain pipe and feed tube on dispensing head and the back dispensing head before described.
The utility model has the advantages that: owing between preceding dispensing head and back dispensing head, fixedly installed connection pipe, on the dispensing head of back, be provided with support tube, and molecular sieve has been filled in the gap in connection pipe, in the degree of vacuum that keeps dispensing head connection pipe inner chamber, increased the anterior cryogenic liquid of inner bag and outside thermally conductive pathways between the end socket, and the manned vehicle liquefied natural gas gas cylinder front support of this structure can play better supporting role to cylinder liner, thereby reduces the static rate of evaporation of manned vehicle liquefied natural gas gas cylinder.
